BUCKLE.

Specification of Letters Patent.

Patented Nov. 30, 1920.

Application filed May 28, 1920. Serial No. 385,279.

taining action may be at any desired place on a strap or the like. i

It is an object of the invention so to form and organize the parts of such a buckle that the pull of both the adjustably-held and fixedly-held portions of a strap or the like act directly on the clamping member to cause it to hold.

Another object of the invention to arrange the parts in such manner that the clamping member easily may be pressed to and released from clamping position.

\Vhcn read in connection with the de 'scription herein, the details and characteristics of the invention will be apparent from the accompanying drawi g. forming part hereof, wherein an embodiment of the invention in a belt-buckle is disclosed, for purposes of illustration.

\Vhile the disclosures herein exemplify what now is considered to be a preferable embodiment of the invention, it is to be understood that it is not the intentionto be limited necessarily thereto in interpretation of claims, as'modification's and adaptations within the limits of the claims can be made without departing from the nature of the invention.

Like reference-characters refer to corresponding parts in the views of the drawing, of which- Figure 1 is a view of the rear side of the buckle;

Fig. 2 is a longitudinal sectional View, on the line 22, Fig. 1;

Fig. 3 is a view of the clamping member as seen when looking at an end of the buckle; and

Fig. 4 is an enlarged sectional view of the clamping member.

Having more particular reference to the drawing, 5 designates a front plate or body portion of the buckle. Oppositely-disposed flanges 6 extend at substantially right angles rearwardly from the front plate. With that plate they afford a guideway for the strap or the like to be adjustably held. Preferably the'plaite and flanges are formed integrally of sheet metal.

Near one end of the buckle, a guide-bar 7 may extend from one flange to the other in separated relation to the front plate and thus act as means to guide the movement of a strap or the like into the buckle and to hold it against the plate.

At or near the other end of the buckle there is mounted a transverse clamping member or tongue 8, which is carried by pintles 9 extending from the ends thereof into seats in the flanges 6. The member 8 is arranged to swing on its pivots and to engage and clamp the end portion of a strap or the like against the body portion of the buckle and thus to hold it in adjusted position when stress or pull is imposed on the held article or member.

In order to facilitate engagement with and holding action of the member 8 against it held part, that member has a comparatively Wide flange 10, which is positioned eccentrically with respect to the pivotal axis of the member and is formed with an engaging-rib 11.

Substantially on the opposite side of the pivotal axis from the flange 10 the member 8 has oppositely-disposed pintles 12, which afford means of pivotally connecting to that member a loop or other suitable part arranged to act as a lever and to have an end portion of a strap or the like fixedly secured thereto. In the embodiment shown that part is made by stamping out from sheetmetal stock and bending to afford a crossbar 13, arranged to have a portion of a strap or the like passed there-around. and side portions 14 having enlarged terminal portions 15 formed with seats into which the pintles 12 extend.

On the side of the pivotal axis toward the crossbar 13 each of the terminal portions 15 has a shoulder 16 positioned to engage the adjacent edge of the member 8 and to move the flange 10 of that member and its rib 11 against the strap or the like to be held adjustably in the buckle when the cross bar 13 is pressed toward the front plate of the buckle. \Vhen that flange and its rib thus have been brought into engagement, its

hold on the adjustably-held strap or the like is increased both by the pull or stress thereof in one direction and by the pull or stress in the other direction of the part iixedly secured to the cross bar 13, whereby a reliable hold is maintained on the adjustably-held part.

In order to facilitate release of the hold of the flange and its rib on the adjustably-held. part, each terminal portion 15 has a lug 1? extending therefrom at a place substantially opposite to its shoulder 16. The lugs 17 are positioned to engage an adjacent portion of the member 8 when the cross-bar 1:5 is moved away from the front plate of the buckle and to move the flange and its rib in the releasing direction-that is, in the direction opposite to movement into holding engagement with the adjustably-held part. With such an arrangement it is easy to loosen the adjustably-held part and to permit it to be moved under the clamping member, and it is not necessary in the opposite direction further to tighten it to release the hold of the flange and its rib thereon.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A buckle comprising a body portion, a tongue thereon arranged to swing on one side of a pivotal axis into engagement with a part to be adjustably held, and a member swing-ably mounted on said tongue having a lug arranged to impart swinging movement thereto.

2. A buckle comprising a body portion, a tongue thereon arranged to swing on one side of a pivotal axis into engagement with a part to be adj ustably held, and a member swingably mounted on said tongue having a shoulder arranged to impart swinging movement thereto.

3. A buckle comprising a body portion, a tongue thereon arranged to swing on one side of a pivotal axis into engagement with a part to be adjustably held, and a member swingably mounted on said tongue having a lug arranged to impart swinging movement thereto in one direction and a shoulder arranged to impart swinging movement there to in the opposite direction.

4. A buckle comprising a body portion, a tongue pivotally mounted thereon arranged to swing on one side of its pivotal axis into engagement with a part to be adjustably held and having pintles on an opposite side of said axis, and a member swingably mounted on said pintles having a lug arranged to impart swinging movement to said tongue in one direction.

5. A buckle comprising a body portion, a tongue pivotally mounted thereon arranged to swing on one side of its pivotal axis into engagement with a part to be adjustably held and having pintles on an opposite side of said axis, and a member swingably mounted on said pintles having a shoulder arranged to impart swinging movement to said tongue in one direction.

6. A buckle comprising a body portion, a tongue pivotally mounted thereon arranged to swing on one side of its pivotal axis into engagement with a part to be adjustably held and having pintles on an opposite sidiof said axis, and a member swingably mounted on said pintles having a lug arranged to impart swinging movement to said tongue in one direction and a shoulder to impart swinging movement thereto in the opposite direction.

7. A buckle comprising a body portion, a. tongue pivotally mounted thereon arranged to swing on one side of its pivotal axis into engagement with a part to be adjustably held and having pintles on an opposite side of said axis, a swingable loop member arranged to have a strap or the like fixedly se cured thereto and having terminal portions into which said pintles extend, one of said terminal portions bein arranged to engage an adjacent part of said tongue and to swing the latter in one direction, and a lug on one of said terminal portions arranged to swing said tongue in the opposite direction.

In testimony whereof I aflix my si nature.

WALTER EUGENE GU ()T.
